The doc states that condor preempts when PREEMPTION_REQUIREMENTS is true and
the submitter has a better (lower priority). This means to me that there is
a default RemoteUserPrio > SubmittorPrio condition. But I agree that the
expression 
PREEMPTION_REQUIREMENTS = (((TARGET.RemoteWallClockTime + (CurrentTime -
EnteredCurrentState)-TARGET.CumulativeSuspensionTime) > 2*(60 * 60)) ||
(MY.NiceUser == True))

Will give us problem when all job have run more than 2 hours as they will
switch back and forth with the priority changing each time. We are going to
fix that. But that still doesn't explain why those jobs weren't preempted.
